A Mercer County Sheriff’s Officer was suspended without pay last month after he allegedly pepper-sprayed a handcuffed woman and then falsified his report detailing the incident, officials said.

Sean Lavin, 42, is charged with two counts of second-degree official misconduct stemming from the Dec. 6 incident and the allegedly falsified report, which was dated Dec. 10, according to the Mercer County Prosecutor’s Office and a complaint filed against Lavin by the sheriff’s office.

“Sergeant Lavin used his department-issued pepper spray to spray an arrestee in the face while she was handcuffed behind her back,” the complaint said. The complaint is dated on Dec. 12.

Prosecutor’s office spokeswoman Casey DeBlasio said the woman was ticketed by Lavin outside of a dance party held at Sun National Bank Center on the night of Dec. 6.

“The victim was issued an improper behavior summons,” DeBlasio said.

Four days later, Lavin submitted a falsified report about the incident, the complaint says. It does not say what information Lavin falsified.
